Just when you thought Laverne Cox couldn't be any more of a badass, she does this...

The Orange Is the New Black star joins Lip Sync Battle this week, taking on her co-star Samira Wiley and going all out for a perfect performance of Nicki Minaj's "Roman's Revenge."

Complete with a leather dominatrix ensemble, plenty of hair flips and even one very (very) high kick, Cox gives the female emcee a run for her own money...But will she come out on top over Wiley? The other OITNB star put on a pretty great performance of Naughty by Nature's "O.P.P." that's no easy competition.

We'll just have to see what happens when the battle goes down on Wednesday night on Spike TV!

Meanwhile, last week, Amber Tamblyn took on America Ferrera in one hilarious and timely rendition of "I Wanna Sex You Up" by Color Me Badd...all the while dressed up as Donald Trump.

Yes, Tamblyn went there, disclosing her idea of what it means to "make America great again" by gyrating her hips on her Sisterhood of the Traveling Pants co-star and even showing off her serious twerking skills.
